Axial Flow API 6D and Short Pattern Nozzle Check Valves
Model: NZ™ & NZS™
Champion Valves, Inc. (CVI) Models NZ and NZS axial flow nozzle check valves are engineered
to provide the longest and most reliable protection of gas and liquid piping systems. CVI’s axial flow non-slam design minimizes water hammer and associated pressure transients. Our design is energy efficient, has an extremely long service life and requires minimal maintenance costs over the life of the valve.
Models NZ and NZS axial flow nozzle check valves are designed with a spring-loaded, center-guided, profiled disc that is guided through bearings in the valve body guide. The valve body is a streamlined axial design with a central diffuser that reduces pressure loss through the valve. Using the latest simulation software and applying years of application experience, Models NZ and NZS have one of the most efficient pressure drop designs available today.
Our commitment to continuous design improvements has led to many unique features, including a hexagonal shaft design that ensures smooth travel of the disc.
